Therefore, Leishi chose GLONASS as a missile-borne satellite positioning system to use, in fact, it is understandable, since there is a scheme that can improve the accuracy of guidance, then why abandon it?

But while there are good things in everything, there are also bad sides, although after the collapse of the Soviet Union, the Russian Federation announced that it would continue the development of GLONASS, promising to build the entire GLONASS GPS in 1993.

By the end of 1993, despite GLONASS's announcement that it had formed an initial combat capability, the number of satellites operating normally was still only 12, and the positioning system could not even cover the entire territory of Russia.

Gross is vast, and in a high latitude area, to complete the full coverage of the country, at least 18 satellites need to be operated in orbit, and in the same year, the United States GPS system also announced that it has all the combat capabilities, and launched all the satellites required for the entire system, with better positioning accuracy than GLONASS (military), from this time, GLONASS has been a comprehensive disadvantage to GPS.

It's still 93 years, and although Yang Hui's butterfly wings to this plane are a little fierce, the impact on the Soviet Union or Russia's space program is almost minimal, so the current GLONASS can only maintain the level of 12 satellites in orbit.

But fortunately, the republic and Russia are distributed in the same meridian area, first of all, to ensure that Russia's own high-precision positioning needs of the GLONASS system, or a large range of coverage of the Republic area, the real area is not covered by most of the Pacific and Atlantic, Western Europe and the southern hemisphere sea area, so it is still very feasible to temporarily use GLONASS as a navigation satellite of Thunderstone.

Of course, if GLONASS has maintained the half-baked level of 12 satellites in orbit, then Yang Hui will not have to go to great lengths to replace the GPS positioning system, anyway, the civilian accuracy of GPS in the later stage will also increase the overall accuracy of the satellite with the continuous replenishment of the network, and even if the civilian version is to be castrated, the accuracy after castration will continue to increase with the overall improvement.

But the biggest problem now is that Yang Hui, who knows the future, is unlikely to accept the use of GPS on the thunderstone in service with the republic, after all, the US imperialists directly turned off the GPS satellite signal coverage in the Taiwan Strait area in 96 years, and there are definitely a lot of things that caused the republic's electronic navigation equipment to not work, if the thunderstone also uses GPS as a guidance signal, you can think of what situation will be faced in the Taiwan Strait area in 96 years.

And Yang Hui can't say this yet, even if he says this kind of thing, who will believe it? When the time comes, it is possible to pull Yang Hui out and convict him of separatism, not to mention that Yang Hui has not yet reached the point of impatience, the leader of a large state-owned company who has come to his current position, he is no longer just representing himself, every action and every sentence involves the future of more than 100,000 men, women, children, wives and children in the southwest of AVIC, so he must act cautiously, so he found a reluctant excuse to replace the use of GPS.

And this excuse is definitely not just the use of precision this one reason, must be multi-pronged: "Secondly, even if it is a civilian GPS navigation terminal, now we want to import large quantities to the domestic use is not easy, our Thunderstone is not only for domestic use at the beginning, optimize the selection of ground precision attack ammunition for lightning fighters, which is also one of the driving forces for our development of Thunderstone guided bombs, and after being exported to foreign countries, the Americans can see at a glance that our Thunderstone uses GPS signals, And even if it is a civilian GPS terminal, the U.S. military prohibits us from installing it on military equipment, so once it is discovered, it will be"

The question raised is very realistic, so that people can quickly understand what the specific situation is after listening, this reason makes the army even more temperless, although just now the army weighed the accuracy of GPS civilian signals, and compared with the glonnass system Wang Xiaoer's embarrassment in the past few years, I feel that it is tolerable to sacrifice some accuracy to ensure reliable positioning.

But this time Yang Hui mentioned that after the use of GPS guidance, the low-cost guided weapon of Thunderstone, which was originally intended to be exported in large quantities, will face the encirclement and suppression of the United States, this kind of thing is not possible, it is the inevitable result of absolutely happening, and if the Thunderstone guided bomb does not have the average development cost of foreign orders, the army of the Republic will definitely not be able to use it!

Finally, GLONASS finally defeated GPS, which means that the Thunderstone satellite guided bomb will temporarily fall to the GLONASS system: "Okay, since you weigh it and think that it is better to use GLONASS satellite system, then you can use GLONASS, anyway, in addition to GPS, we only have this option, who said that we don't have this thing ourselves, after all, it is difficult for everyone these years!" ”

Maybe he thought of some other things, and for a while, the small living room was also filled with a suffocating atmosphere, Yang Hui was a little unhappy, and he used practical actions to break this strange atmosphere.

Concentrated, using all the essence, Yang Hui explained again: "We chose GLONASS, which is also a well-thought-out choice. First of all, GLONASS's satellite receiving terminal chip is made by Russia itself, although it will lag behind the United States in performance, but it will not be banned from sale to us, so it can be purchased in batches in a bright and bright way; Secondly, GLONASS's ICD signal interface control file has been made public all over the world, and even we can manufacture terminal receiving chips in small batches in the laboratory for the safety of use, but on the other hand, GPS, there is no sign of disclosing this aspect of the document, so in all aspects, we are more inclined to choose GLONASS. ”

All this, Yang Hui is talking about the benefits of GLONASS, but its disadvantages Yang Hui has not mentioned a word, it is really unnecessary to say these things now, at least Yang Hui clearly remembers that after the collapse of the Soviet Union, 91 to 93 years is indeed the era when GLONASS stopped developing, but with the smooth networking of GPS in 93, this seriously stimulated Russia, plus Russia at this time can be regarded as an aftertaste, knowing that those NATO countries are unreliable, That's why he threw a lot of money into GLONASS.

Therefore, during the period from 93 to 96, the GLONASS system continued to launch satellites to supplement the network, and at its peak in January 96, it even reached the level of 24 satellites in orbit, which also made GLONASS have the ability to provide global positioning and navigation for the first time.

Later, with Russia's economic crisis in 96, the country's economy was hit hard again and the Great Depression, the entire GLONASS system because of the low life of satellites, only 3 years of service life, in the second half of 96 there were only 22 satellites in orbit, in 97 it fell to the level of 16, and then it became less and less, until 2002 it even fell below double digits, leaving only 8 satellites in orbit, So GLONASS was the most brilliant moment in the pan in the first half of '96, and then there was nothing to see.

But this short-lived moment is absolutely good news for the republic, after all, the most critical time for the republic in the Taiwan Strait is also the first half of 96 years, when the GLONASS signal is the most stable, the best accuracy, the use of GLONASS as the positioning and navigation system of the thunderstone, at this time is also the highest precision since mass production, when the time to make the accuracy of the thunderstone within 15 meters is definitely not a joke.

And these can only be known by Yang Hui himself, and he can't come up with more reasons to convince the army, but fortunately, the army finally agreed to Lei Shi's use of the GLONASS system as a navigation satellite, which saved a lot of saliva.

Of course, if you have a little more money at hand, Yang Hui is actually more willing to use similar to the experience of the Republic in the Beidou system, and directly launch the three satellites of the regional positioning and navigation system "Beidou No. 1", although the accuracy is not very good, but after all, it can cover the territory, territorial waters, and airspace of the entire Republic.

However, in view of the overall development of the Republic in the integrated chip industry throughout the 90s, it is also quite difficult to develop a terminal chip that can be compatible with a variety of satellites, and now Leishi needs to rush to complete the project, and under the requirements of finalizing and equipping Leishi before 96 years, it is impossible to have enough time to wait for the development of satellite terminal chips.

Moreover, Yang Hui himself actually has some personal ideas in it, according to the current way of thinking, you can roughly think about it in 96 years, the army's other equipment that uses GPS navigation equipment is suddenly unusable, and the accuracy of the Thunderstone guided bomb using GLONASS at this time is very good, the highest accuracy can reach within 15 meters, but with the rapid yang of the GLONASS system after 96 years. wilted, and soon the army would watch the guidance accuracy of the originally awesome Thunderstone getting lower and lower.

At this time, I am afraid that there is no need for Yang Hui to say anything, the army that eats the marrow and knows the taste will definitely scream to develop a global positioning system that can be in their own hands, and whether it is to take advantage of the economic crisis in Russia in 96 to copy the Glonas, or to develop the Beidou navigation system by itself, it will be very beneficial anyway, but at least it will not run to add the ass of the Europeans to engage in the Galileo system.
